## What it is
CMAK (Cluster Manager for Apache Kafka, formerly Kafka Manager) is a web-based tool for managing and inspecting Apache Kafka clusters. It supports multi-cluster management, topic operations, partition reassignment, and optional JMX-based metrics polling.

## Use cases
- manage multiple kafka clusters from one web ui
- inspect kafka topic and consumer offsets
- reassign kafka partitions across brokers
- create and delete kafka topics
- run preferred replica election
- monitor kafka broker metrics via jmx

## When to choose
- you run older Kafka 0.8-0.11 clusters and need a management UI
- you want a self-hosted tool for topic and partition administration
- you need visibility into consumer lag and broker state

## When to avoid
- you run modern Kafka versions (2.x+) where the project is no longer actively developed
- you need Kafka Connect or Schema Registry management
- you want a cloud-managed Kafka monitoring solution

## Facets
- artifact type: application
- maturity: maintenance
- function: monitoring, developer-tools, gui
- domain: big-data, databases, self-hosted
- platform: jvm, self-hosted
- tags: kafka, cluster-management, scala, web-ui, apache-kafka, devops, web-server
